Wildfire smoke from Canada continues to impact air quality across the US Northeast and Midwest, prompting air quality alerts. Breathing this smoke is likened to smoking half a pack of cigarettes daily, posing significant health risks, especially for those with pre-existing conditions. Emergency room visits for respiratory issues have increased dramatically during smoke events. Experts advise limiting exposure by staying indoors with closed windows, using air filters, and wearing N95 masks if going outside. Climate change is exacerbating the frequency and intensity of wildfires, increasing smoke exposure nationwide.
